Abstract
Description
- The present application claims the benefit of U.S. Provisional Application Ser. No. 61/973,751, filed Apr. 1, 2014, the contents of which are expressly incorporated herein by reference.
- Not Applicable
- 1. Technical Field
- The present disclosure relates generally to a power supply management device for a home, and more specifically, to a device capable of monitoring the supply of power from a power grid, drawing power from an electric vehicle and supplying the power to the home in the event of power loss from the grid.
- 2. Description of the Related Art
- Electric vehicles have grown in popularity in recent years due to their desirable fuel economy and their reduced emissions relative to conventional internal combustion vehicles. Electric vehicles are typically powered by one or more electric motors, which use energy stored in on-board batteries for driving the motor. After driving an electric vehicle for a period of time, the energy stored in the batteries becomes depleted, and therefore, electric vehicles are designed to be recharged to replenish the stored energy in the batteries.
- Recharging of the batteries in an electrical vehicle typically occurs by connecting a power cable having a specially designed socket to a corresponding outlet formed on the vehicle. Typically, the owner of an electrical vehicle will have a charging cable at their home to allow the vehicle to recharge when the vehicle is parked at the home. In addition to charging at one's home, there has been a rapidly expanding network of public charging stations, which has made it easier to charge electric vehicles away from the home. For instance, government agencies, automakers, charging equipment manufacturers, etc., have contributed to the growing number of public charging stations.
- It is understood that in some instances, the power grid supplying power to the home may experience a power loss. For instance, a severe weather event may cause a power loss, or the power loss may also be caused by an overload on the power grid, as commonly occurs in the hot summer months. In most instances, the power grid is the sole supply of power to the home and the vehicle recharging in the home, and thus, when power is no longer supplied from the grid, the home experiences a power outage and the vehicle stops recharging. A power loss from the power grid is typically a very undesirable occurrence since most households are dependent on the power grid to provide electricity for such basic needs as light, warm water, and refrigerated food. In the winter and summer months, the home may also use electricity from the grid to power a heater or air conditioner to maintain a safe and comfortable temperature within the home.
- The batteries in an electric vehicle located at a home experiencing a power loss may have a sufficient amount of stored power to provide electricity to the home. For instance, the power loss may occur after the batteries in the vehicle have completely recharged. Furthermore, in view of the prevalence of publically available charging stations, the battery power of the electric vehicles may not be as depleted when the vehicles return to the home, and as such, even if the power loss occurs shortly after the vehicle returns to the home, the vehicle batteries may still have a good amount of stored power. Accordingly, an electric vehicle located at a home experiencing a power loss may be a good source of supplemental electrical energy. However, the conventional connection between the electrical network in the home and the vehicle is that power flows one way, namely, from the home to the vehicle, not from the vehicle to the home.
- Accordingly, there is a need in the art for a power management device which monitors the supply of power from a power grid to a home, and draws power from a vehicle for supply to the home in the event of a power loss from the grid. Various aspects of the present disclosure address this particular need, as will be discussed in more detail below.
- In accordance with the present disclosure, there is provided a device and corresponding method for managing the communication of power to a home from an external power source. In a first, normal, operational mode, power is delivered from a power grid to a rechargeable vehicle and the home. However, in the event of power loss from the power grid, stored power is drawn from the vehicle and is supplied to the home to mitigate the consequences of grid power loss.
- According to one embodiment, there is provided a power switching unit adapted for use with a power grid, a home power network, and a vehicle having a vehicle power network. The power switching unit includes a first power port configured to be connectable to the power grid to receive power therefrom, a second power port configured to be connectable to the vehicle power network, and a third power port configured to be connectable with the home power network. A switch is in electrical communication with the first power port, the second power port, and the third power port, with the switch being transitional between a first position and a second position. In the first position, the switch places the first power port in electrical communication with the second power port and the third power port to enable the power grid to provide power to the vehicle power network and the home power network. In the second position, the switch places the second power port in electrical communication with the third power port, to allow the electric vehicle to provide power to the house power port.
- The first power port may be configured to detect a power loss from the power grid. The switch may be configured to automatically switch from the first position to the second position in response to a detected power loss by the first power port. The switch may also be configured to automatically switch from the second position to the first position in response to detection of power from the power grid. The switch may be configured to isolate the first power port from the second power port and the third power port when the switch is in the second position.
- The power switching unit may additionally include a user input circuit adapted to receive a switch signal from a user, with the switch being configured to switch modes in response to receipt of the switch signal. The user input circuit may include a wireless communication circuit capable of receiving the switch signal via wireless communication.
- The first power port may be configured to receive 100-240V AC from the power grid. The second power port may be configured to transmit 100-240V AC to the vehicle power network when the switch is in the first mode, and receive 100-240V AC from the vehicle power network when the switch is in the second mode. The second power port may be an IEC 62196 connector.
- The power switching unit may further include a control unit capable of generating a command signal to the vehicle power network to provide power to the second power port.
- According to another embodiment, there is provided a method of managing the communication of electrical power between a power grid, a vehicle power network, and a home power network. The method includes receiving electrical power from the power grid at a first power port. The electrical power received from the power grid is delivered to a second power port adapted to communicate electrical power to the vehicle power network for charging the vehicle, and a third power port adapted to communicate electrical power to the home power network. The method further includes the step of detecting a loss of electrical power from the power grid at the first power port, and receiving electrical power from the vehicle power network at the second power port subsequent to the detected loss of electrical power from the power grid. The electrical power received at the second power port is delivered to the third power port for supplying electrical power to the home.

-
FIG. 1 depicts apower management system 10 for managing power between apower grid 12, ahome 14, and anelectric vehicle 16. As will be described in more detail below, the power is managed through apower switching unit 18 which is in electrical communication with thepower grid 12, thehome 14, and theelectric vehicle 16. During normal conditions, i.e., when power is being received from thepower grid 12, thepower switching unit 18 delivers received power from thegrid 12 to theelectric vehicle 16 for recharging thevehicle 16, as well as delivering power to thehome 14 for providing power to the electrical appliances therein. However, in the event of a power outage which results in power loss from thepower grid 12, thepower switching unit 18 draws stored power from thevehicle 16 and delivers that vehicle power to thehome 14. Accordingly, thepower switching unit 16 may allow an owner of anelectric vehicle 16 to tap into the stored energy of thevehicle 16 in the event of a main power loss from thegrid 12. Therefore, theelectric vehicle 16 may serve as a backup power source to thehome 14. - As used herein, the term “power grid” refers to an interconnected network for delivering electricity from one or more suppliers to one or more customers. The supplier may be a utility company which generates the electricity at a power station, e.g., nuclear, hydroelectric, wind farm, solar, etc.
- As used herein, the term “electric vehicle” refers to any vehicle having stored electrical energy, including those vehicle capable of being charged from an external electrical power source. This may include vehicles having batteries which are exclusively charged from an external power source, as well as hybrid-vehicles which may include batteries capable of being at least partially recharged via an external power source.
- The ability to switch the source of power to the
home 14 is made possible by thepower switching unit 18, which includes apower grid port 20 connectable to thepower grid 12, avehicle port 22 connectable to avehicle power network 24 associated with thevehicle 16, and ahome port 26 connectable to ahome power network 28 associated with thehome 14. Thevehicle power network 24 includes the battery or batteries located on thevehicle 16, which provides power to the vehicle's electrical systems. Thevehicle power network 24 may further include a plug or connector for connecting thevehicle power network 24 to an external power source for recharging the batteries. Thehome power network 28 generally includes the home's electrical network which is capable of distributing received electrical energy to the electrical outlets and appliances located in thehome 14. - The
power grid port 20 and thehouse port 26 may include terminals which are hard wired to thepower grid 12 andhome power network 28, respectively, to create a more permanent connection between thepower switching unit 18 and thepower grid 12 andhome power network 28. Alternatively, thepower grid port 20 andhome port 26 may include plug-type connectors which allow for more rapid connection/disconnection of thepower switching unit 18 to thepower grid 12 andhome power network 28. The ability to rapidly connect and disconnect thepower switching unit 18 facilitates the deployment of thepower switching unit 18 in times of emergency, e.g., widespread power loss. Thevehicle port 22 may include a plug-type connector configured to detachably engage with the charging port/outlet on thevehicle 16. Thevehicle port 22 may be required to comply with one or more standards associated with rechargeable vehicles. For instance, in one embodiment, thevehicle port 22 is an IEC 62196 compliant connector, although other connectors known in the art may also be used. - According to one embodiment, the
power grid port 20 may be configured to receive 100-240V AC at a current in the range of 32-64 Amps from thepower grid 12. Likewise, thevehicle port 22 may be configured to transmit and receive 100-240V AC at a current in the range of 32-64 Amps to and from thevehicle power network 24. Those skilled in the art will recognize that the foregoing values are exemplary in nature only, and that the parameters may change depending on the infrastructure of thepower grid 12, thevehicle power network 24 and thehome power network 28. - The
power grid port 20,vehicle port 22, andhome port 26 are each in electrical communication with aswitch 30 capable of routing electrical power between theports switch 30 is configured to be transitional between a first position and a second position. In the first position, theswitch 30 places thegrid port 20 in electrical communication with thevehicle port 22 and thehome port 26 to enable thepower grid 12 to provide power to thevehicle power network 24 and thehome power network 28. In the second position, theswitch 30 places thevehicle port 22 in electrical communication with thehome port 26, to allow theelectric vehicle 16 to provide power to thehome port 26. During normal operational conditions, thepower switching unit 18 will draw power from thepower grid 12 to provide charging power to theelectric vehicle 16 and to thehome 14 by way of thevehicle port 22 andhome port 26, respectively. In this respect, during normal operating conditions, the power from thegrid 12 is supplied to both thehome 14 and thevehicle 16. However, in the event of a power outage on thegrid 12, thepower switching unit 18 is capable of supplying stored electrical energy in thevehicle 16 to thehome 14. In this respect, thepower switching unit 18 allows thevehicle 16 to serve as the primary power feed to thehome 14, at least for a limited period of time. Once power on thegrid 12 is made available again, theswitch 30 may transition from the second position back to the first position, to draw power from thegrid 12 and supply power to thehome 14 and thevehicle 16. According to one embodiment, theswitch 30 may be configured to isolate thevehicle 16 andhome 14 from the downedpower grid 12 by isolating thegrid power port 20 from thevehicle port 22 and thehome port 26 when theswitch 30 is in the second position. Once theswitch 30 transitions back to the first position, the communication between thepower grid 12,vehicle 16, andhome 14 may be restored by placing thepower grid port 20 in communication with thevehicle port 22 and thehome port 26. - Operation of the
switch 30 may be controlled by acontroller 32, which is in communication with theswitch 30, theports power switching unit 18 includes apower grid sensor 34 capable of detecting the power supplied from thepower grid 12, as well as a loss of power from thegrid 12. Thepower grid sensor 34 may be integrated into thepower grid port 20 or may be formed separate from thepower grid port 20. Thepower grid sensor 34 is in communication with thecontroller 32 to provide thecontroller 32 with status information regarding power received from thegrid 12. In particular, when power is received from thepower grid 12, thepower grid sensor 34 detects the power and generates a POWER RECEIVED signal, which is then sent to thecontroller 32. If thesensor 34 detects a loss of power, thesensor 34 generates a NO POWER signal, which is then sent to thecontroller 32. When thecontroller 32 receives the POWER RECEIVED signal, thecontroller 32 generates a FIRST POSITION command signal, which is transmitted to theswitch 30. Theswitch 30 is configured to assume the first position in response to receipt of the FIRST POSITION command signal. When thecontroller 32 receives the NO POWER signal from thepower grid sensor 34, thecontroller 32 generates a SECOND POSITION command signal, which is transmitted to theswitch 30. Theswitch 30 is configured to assume the second position in response to receipt of the SECOND POSITION command signal. According to one embodiment, thecontroller 32 automatically generates the FIRST POSITION command signal in response to receipt of the POWER RECEIVED signal, and the SECOND POSITION command signal in response to receipt of the NO POWER signal. In other words, the FIRST and SECOND POSITION command signals may be generated without any input by the user. - According to another embodiment, the
power switching unit 18 may include amanual input circuit 36 in electrical communication with thecontroller 32 and adapted to allow a user to selectively transition theswitch 30 between the first and second positions via manual input (e.g., pressing a button on the power switching unit 18). Along these lines, themanual input circuit 36 may generate and transmit FIRST POSITION and SECOND POSITION command signals to thecontroller 32 in response to respective inputs received from the user via themanual input circuit 36 for selectively positioning theswitch 30. Themanual input circuit 36 may be associated with a switch, dial, keypad, physical button or a virtual button on a touch screen display, etc., located on thepower switching unit 18. - According to another embodiment, the
power switching unit 18 may include awireless input circuit 38 in electrical communication with thecontroller 32 and adapted to allow a user to provide input commands to thepower switching unit 18 via wireless communication. The ability to wirelessly communicate control signal may be desirable for allowing the user to control operation of thepower switching unit 18 via a mobile communication device 40 (e.g., a smartphone, tablet computer, etc.). In this regard, thewireless input circuit 38 may be capable of transmitting and receiving wireless signals in several different wireless protocols, including, but not limited to WiFi, Bluetooth™, GSM communications, or other wireless protocols known in the art. When thepower switching unit 18 is used with asmartphone 40, the user may download a smart phone application (i.e., an “app.”) which provides the software on thesmartphone 40 necessary for operating thepower switching unit 18. Along these lines, when the app. is downloaded onto thesmartphone 40, the user can selectively generate and transmit FIRST POSITION and SECOND POSITION command signals which are received by thewireless input circuit 38 and relayed to thecontroller 32 for selectively positioning theswitch 30. - It is contemplated that when using the
power switching unit 18 during a loss of power from thepower grid 12, a user may not want to completely drain all of the power from thevehicle 16. In this respect, the user may want to leave enough power in thevehicle 16 to drive the vehicle 16 a preset minimum number of miles (e.g., 35 miles). Somevehicles 16 may come equipped with a built-in shutoff feature, which prevents the further drawing of power therefrom once the stored power levels in thevehicle 16 reach a prescribed minimum power level. However, if thevehicle 16 is not equipped with such a feature, thepower switching unit 18 may include ashutoff circuit 40 which monitors the power level in thevehicle 16 and instructs thecontroller 32 to cease drawing power from thevehicle 16 when the power level in thevehicle 16 reaches the prescribed minimum power level. - The
power switching unit 18 may include a built-indisplay 42 for providing information, preferably in a digital format, related to the energy usage from thegrid 12 when theswitch 30 is in the first position, and energy drawn from thevehicle 16 when theswitch 30 is in the second position. - The
power switching unit 18 may further include a built-in voltage regulator and powersurge safety mechanism 44 for protecting thepower switching unit 18, as well as thehome 14 andvehicle 16 coupled to theunit 18. - According to one embodiment, the
controller 32 may be configured to not only control the communication of power between thepower switching unit 18 and thevehicle 16, but also the communication of data therebetween. In this respect, thepower switching unit 18 may include adata transceiver 46 which is operatively connectable to a corresponding transceiver located on thevehicle 16. Thecontroller 32 may have a database of stored communication protocols which enable communication with a number ofdifferent vehicles 16. - The
power switching unit 18 may further include a retractable power cable with a line overheat temperature sensor with safety cut-off to prevent overheating of the cable. In this respect, the cable is required to be fully extended before charging or discharging can start. This safety feature is intended to mitigate overheating by a coiled cable. - Although the foregoing describes the use of the
power switching unit 18 for drawing power from thevehicle 16 and supplying such power to ahome 14 in the event of power loss from thegrid 12, it is contemplated that thepower switching unit 18 is also adapted to allow power to be drawn from thevehicle 16 even if power is not lost from thegrid 12. In this respect, a user may choose to draw power from thevehicle 16 by inputting a command through one of theinput circuits vehicle 16, theswitch 30 may isolate thegrid 12, even though thegrid 12 is capable of providing power. When the user wants to switch back to thegrid 12, the user may once again use one of theinput circuits vehicle 16. For instance, the user may instruct thepower switching unit 18 to draw power from thevehicle 16 for a prescribed period of time, and then switch back to drawing power from thegrid 12. For instance, some utility companies place a premium on electricity during certain times of the day. Therefore, a user may instruct thepower switching unit 18 to draw power from thevehicle 16 during those premium hours, based on the condition that thevehicle 16 is connected to thepower switching unit 18, and then switch back to drawing power from thegrid 12 when the rates have dropped. - Although the foregoing describes the
power switching unit 18 for use in connection with a residential home, it is understood that the term “home” as used herein may refer broadly to any facility having a dedicated power network. In this respect, thepower switching unit 18 may be used at a commercial facility for providing backup power via one or moreelectric vehicles 16. This may be particularly beneficial for a company which owns a fleet ofelectric vehicles 16, wherein the fleet ofvehicles 16 may collectively supply power to the commercial facility in the event of a grid power loss. - The particulars shown herein are by way of example only for purposes of illustrative discussion, and are not presented in the cause of providing what is believed to be most useful and readily understood description of the principles and conceptual aspects of the various embodiments of the present disclosure. In this regard, no attempt is made to show any more detail than is necessary for a fundamental understanding of the different features of the various embodiments, the description taken with the drawings making apparent to those skilled in the art how these may be implemented in practice.
